+- The old wxADJUST_MINSIZE behaviouris now the default behaviour for
+  sizer items that are windows.  This means that GetAdjustedBestSize
+  will now be called by default to determine the minimum size that a
+  window in a sizer should have.  If you want to still use the initial
+  size (and not the BestSize) then use the wxFIXED_MINSIZE flag.  When
+  windows are added to a sizer their initial size is made the window's
+  min size using SetSizeHints, and calls to wxSizer::SetItemMinSize
+  are also forwarded to SetSizeHints for window items.
